Hey folks, maybe this is a real dumb question, but can I stack/benefit from 2 of these stratagems?

Slayers of Shadows is used before choosing a house mortan unit to shoot..until the end of the phase, you ignore all to-hit modifiers.

Can I combine this with the Skyreaper protocols for helverins that is used before you make a shooting attack?

It makes sense in my head, but maybe I'm missing something..

They seem to work together, unless there is an FAQ I missed.

Yes, they work together. Re-rolls are not a modifier.
